ACS 5.2 Authentication

I have cisco ACS 5.2 server which is integrated with Active directory .Now users are not able to login to one perticular device ,which was working fine for last 2 month .Authentication request are not coming to ACS .we didnt made any changes in ACS side .

For testing purpose we have configured the device with Cisco ACS 4.2 ,which is not integrated with AD then its working fine and user is able to login .

Kindly help me ..

If no request is hitting ACS 5, then there's nothing you can do on ACS can you ?

I suggest checking your device config and check with debugs/trace if it is really sending something towards acs 5.

Maybe give more info about that device ?

Deive is an SBC Switch .issue is resolved now .

we have two servers ,one is primary  (ACS1 )and other is secondary (ACS 2)  ,which is replicating from primary .

In all network elements we configured ACS1 as primary and ACS2 as secondary .

I was able to ping that device from ACS 1 and user is able to ping ACS 1 from that device too ,after he logged in locally .

I have investigated the above issue in network level  and understood that radius packets are not coming to ACS1 and it is going ACS2 , but at that time also we can not see any authentcation logs  from this device in our  primary/secondary server .even though user are contineously getting failed authentcation .

Now  we have configured ACS2 as primary and ACS1 as secondary in that perticular device .and it start working .

I still can not understand the root cuase for the same ,even rest of the all devices in that NDG (Same location and same subnet ) is sending authencation request ACS1 and working fine .
